A Review of Hamilton Sunscreens

A Review of Hamilton Sunscreens

Hamilton Optimal is far from ideal...


Australian homo sapiens terminally oxidize due to skin cancer processes at a rate of one organism per hour.

The situation amounts to at least two thirds of us being diagnosed with skin cancer in our lifetimes.

An inability to ideally manage daily, incremental exposure to UV is also the primary means by which patients permanently set in motion processes which alter DNA to quickly destroy the physical and aesthetic, social value of their skins.

Those who choose to deliberately expose themselves to solarium radiation before the age of 35, perhaps heeding the uncaring logic of operators such as Body Bronze, can increase the risk of melanoma skin cancer by 75%.

Prevention is the best strategy because we must now operate from the presumption that a patient will, literally, more likely than not, develop skin cancer — that all patients are en route to skin cancer if they are not mindful in their approach to their skin as an organ.

What then to make of a situation where one of Australia's most respected and readily available sunscreen brands, Hamilton, appears to make it deliberately difficult to choose the right sunscreen, and that even at its highest SPFs manages real-world protection of half or less than half that of other sunscreens of lesser SPFs?

What is the point of a range marked by lesser and greater protection?

Does anyone actually want, or need, less protection in a sunscreen?

Incomplete sun protection (photoprotection) destroys primary constituents of healthy and physically youthful skin (collagen, elastin, proteoglycan and skin cells), in winter and summer, irrespective of cloud coverage to arrive at symptoms of permanent, premature aging (photoaging) and, in the worst case scenario but increasingly frequently, skin cancer.

Three international, well-controlled studies show a higher incidence of permanent skin damage in individuals using inadequate sunscreens, which suggests the spiraling incidence of melanoma skin cancer and accelerated skin aging are partly or largely due to uneducated use of and reliance on inadequate sunscreens.

The Hamilton Family 15 Range

Contains 4-methylbenzylidene camphor, a sunscreen not recommended for use on children under 12 because it appears to have undesirable hormone-like effects on the thyroid gland. It is thought to be safe for use by adults, however it is beyond question that this sunscreen is absorbed and metabolized by the body.

Contains octyl methoxycinnamate (also known as Octinoxate), which while being the leading UVB sunscreen ingredient, is also absorbed and metabolized by the body, and is associated with allergies. Unless this sunscreen ingredient is encapsulated to prevent systemic absorption, it cannot really be regarded as ideal or perhaps even safe for regular use, which is a problem given that only "chronic" photoprotection is meaningfully therapeutic.

Contains the chemical sunscreen methoxydibenzoylmethane (also known as Parsol) as a UVA block, however again it is unencapsulated and therefore metabolized by the body.

Further this chemical sunscreen is not an adequate UVAII block and frequently causes allergic reactions, so cannot be considered suitable for ongoing use.

Contains the oil-soluble chemical, Bemotrizinol, which improves the photostability of the sunscreen ingredients, and while not approved in all countries, is thus-far considered safe.

A maximum of 40 minutes water resistance is available.

No sunscreen in the Hamilton Family 15+ Range protects against photoaging, only burning, tanning, and partially against the likelihood of skin cancer.

The Hamilton Family 30+ Range

Is essentially the same as the Hamilton Family 15 range, however with one exception contains the physical sunscreen titanium dioxide, which while not absorbed by the body, is not an adequate block against long wave UVA radiation, and therefore offers no protection against those rays which are proven to cause photoaging changes in human skin. The percentage used (2%) is paltry in any event. Titanium dioxide should be present at around 10%.

The Hamilton Family Sunscreen Spray SPF 30+ is especially likely to be applied too lightly and indiscriminately.

Research indicates that the real-life SPF of such a sunscreen texture will be in the order of 2 to 4, which isn't reassuring given the formula's pre-existing inadequacies.

Clinical experience backs up the theory — individuals burn/tan or develop hyperpigmentation (including freckles) when using such sunscreens.

This particular sunscreen doesn't contain titanium dioxide and contains less methylbenzylidene camphor than Hamilton Family Sunscreen Milk SPF 30+ so is the least protective of all the sunscreens within the Family 30+ range.

A maximum of 4 hours water resistance is available.

This range isn't a preferable answer to photoaging or skin cancer, yet still manages to make the Family 15+ Range seem redundant.

Hamilton "Optimal" SPF 30+

Seems to be little more than a marketing creation, because Hamilton Optimal is anything but what its name would lead you to believe.

You'd think it'd be Hamilton's best sunscreen, and at the very least somewhat better than the basic Family 30+ Range, but its not.

Indeed, it offers a touch less UVA protection.

The chemical sunscreen is unencapsulated so will be absorbed and metabolized by the body, problematic as per the SPF 15 and SPF 30+ Family Ranges discussed above.

Optimal probably just describes the product texture, not its substance.

Hamilton Sportblock SPF 30+

Is identical to the Hamilton Family 30+ range in sunscreen ingredients and percentages, only the texture and preservatives are different, making it less likely it'll slip into your eyes and cause irritation.

The chemical sunscreen in unencapsulated so will be absorbed and metabolized by the body, problematic as per the SPF 15 and SPF 30+ Family Ranges discussed above.

Hamilton Quadblock SPF 30+ Range

Feels heavier and thicker than the Hamilton SPF 30s in other categories, but is no more adequate.

Quadblock sunscreens only contain three sunscreen ingredients, not four like many of Hamilton's others, so perhaps should be called Triblock.

The thicker, whiter texture probably leads individuals to believe it is more protective or hard-wearing than other sunscreens, yet Hamilton Quadblock contains less absorbable UVA block than their other SPF 30+ sunscreens.

Nothing in Quadblock prevents photoaging.

The chemical sunscreen in unencapsulated so will be absorbed and metabolized by the body, problematic as per the SPF 15 and SPF 30+ Family Ranges discussed above.

Hamilton Sensitive SPF 30+ Range

Foregoes the irritation potential of unencapsulated chemical sunscreens by using zinc and titanium dioxide, however turns skin white and floats visibly over the surface.

The ingredient listing reveals that the titanium dioxide content is only 2.9%, while other SPF 30+ sunscreens provide 10%.

Because zinc oxide completely overlaps and extends beyond the protection offered by titanium dioxide (from 290 to 380 nano metres instead of from 290 to 340 nano metres), the titanium dioxide content is therapeutically redundant.

It is likely that more titanium dioxide than zinc oxide is present because it is cheaper to formulate a cosmetically acceptable sunscreen in this manner.

Hamilton Every Face SPF 30+ seems to illustrate this, because its formula represents the reverse situation and the product volume is smaller.

The disparity and harm to individuals is made possible by the TGA being flawed in its approach to SPF regulation.

Hamilton Toddler SPF 30+ Range

For babies over 6 months and small children, Hamilton have foregone the protective stinginess of the Sensitive SPF 30+ range.

There is more physical zinc oxide than titanium dioxide, and the safest chemical sunscreen (octyl methoxycinnamate) is used, although unfortunately it is unencapsulated so will still be absorbed and metabolized by the body.

However, the zinc oxide content is still too low.

Other SPF 30 sunscreens encapsulate their chemical sunscreens and use 7% zinc oxide.

As per the Hamilton Sensitive SPF 30+ Range, the Hamilton Toddler sunscreens lean on the TGA's flawed approach to SPF, although to a lesser degree.

Babies and small children should use zinc oxide alone.

The sunscreen is too thick, white and pasty for adults to use on their faces (unless they're outdoor circus performers), and is uncomfortable for whole body application.

Nevertheless, if you must use a Hamilton sunscreen, and aren't about to apply Hamilton Everyday Face SPF 30+ to your entire body, here the Toddler Cream is as close to ideal as things are going to get.

Hamilton Everyday Face SPF 30+ Sunscreen

The best Hamilton sunscreen from a purely and immediately therapeutic perspective, it contains the most zinc oxide of any Hamilton Sunscreen, but like the "sensitive" and "toddler" sunscreens features redundant titanium dioxide, exploiting government-endorsed flaws in SPF evaulation.

Again, the chemical components of this sunscreen are unencapsulated so are absorbed and metabolized by the body, and are associated with allergies.

That this sunscreen is specifically marketed as being suitable for everyday facial use without preventing chemical absorption is highly problematic, because we do not yet know the consequences of forcing the body to process chemical sunscreens with little or no break.

It is not out of the question that such sunscreen use may ultimately prove to be of some net harm.

Further, other sunscreens offer considerably more protection against skin cancer and photoaging at SPF 20 (non-plus) than this SPF 30+, and others still more protection at SPF 30 (non-plus).

Hamilton Everyday Face SPF 30+ Sunscreen does not prevent photoaging.

Conclusions

  • No Hamilton sunscreen represents anything like ideal photoprotection, particularly for preventing photoaging.

  • Hamilton "Optimal" is sub-par;

  • Hamilton "Family" sunscreens are not especially skin-caring;

  • Hamilton "Family Sunscreen Spray SPF 30+" should simply be avoided, so long as its replaced by something better (not difficult given its protective paucity);

  • The Hamilton "Toddler" range and "Everyday Face SPF 30+" sunscreens are superior among the entire collection, but government-endorsed flaws in SPF calculation assist disingenuous protection and encourage inadvertent permanent harm to individuals' skins.

Individuals wishing to actually prevent skin cancer and photoaging (responsible for approximately 90% of the signs of visible aging) will need to be familiar with sun exposure realities and actually implement flawless photoprotection.
